China SiC Coated Barrel Manufacturer, Supplier, Factory

In the preparation of high-quality and high-yield silicon carbide substrates, the core requires precise control of production temperature by good thermal field materials. Currently, the thermal field crucible kits mainly used are high-purity graphite structural components, whose functions are to heat molten carbon powder and silicon powder as well as to maintain heat.

For industrial-scale production of silicon carbide substrates, the success of a single growth run is not the end goal. The real challenge lies in ensuring that crystals grown across different batches, tools, and time periods maintain a high level of consistency and repeatability in quality. In this context, the role of tantalum carbide (TaC) coating goes beyond basic protection—it becomes a key factor in stabilizing the process window and safeguarding product yield.

This article mainly discusses the respective process advantages and differences of Molecular Beam Epitaxy process and Metal-organic chemical vapour deposition technologies.

8-inch SiC epitaxial furnace and homoepitaxial process research

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.
